v. PAONE OIL MEASURING AND DISPENSING CAN Filed Julie 17, 1929 Patented Apr. 29, 1930 VINCENZO PAONE, OF UTICA, NEW YORK OIL MEASURING AND DISPENSING GAN Application filed June 17,

The invention relates to the hand-carried oil cans used at automobile service stations for carrying measured quantities of oil to automobiles and discharging it into the usual reservoirs thereof for lubricating purposes. Cans of this type are provided with a valve to either prevent or permit discharge of oil, and it is the object of my invention to provide a new and improved construction in which unique provision is made for opening and closing the valve and holding it in open position. l

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing. 7

Fig. 1 is a perspective view showing one form of the invention. 1

Fig. 2 is a vertical sectionalview through the device shown in Fig. 1 showing the movable parts in valve-closed position.

Fig. 3 is a view similar to Fig. 2 but illustrating the relation of parts when they arrive almost at complete valve-open position.

Fig. 4 is a view similar to Fig. 3 but showing a different form of construction.

In the drawing above briefly described, the numeral 5 denotes the usual oil measuring container which is open at its top and pro-' vided near its upper end with a vertical handle 6. The bottom 7 of the container 5 declines to an outlet opening 8, and an oil discharge pipe 9 communicates with this opening and extends horizontally under the bottom 7, said pipe being connected with a flexible tube 10 having a nozzle 11. This nozzle is preferably provided with a hook 12 to engage the rim of the container 5 when the device is not being used for discharging oil.

A flat-sided, vertically disposed, tubular guide 13 is secured in the pipe 9 in alinement r with the opening 8, said guide slidably but non-rotatably receiving the fiat-sided lower end 14 of a vertical rod 15 which extends to the open top of the container 5. Near its upper end, this container is provided with a second rod guide in'the form of an inwardly projecting rigid bracket 16 having an open- 1929. Serial No. 371,595.

ing 16 through which the rod 15 passes. slidably. Rod 15 is provided with a valve 17 which normally seats upon the bottom 7 and closes the opening 8, and said rod is forced normally downward to valve-closed position, by an appropriate spring 18. The rod however is provided with a notch 19 adapted to snap into engagement with the upper guide 16 when the rod 15 is completely raised to valve-open position, thereby holding the valve 17 open while the oil dis-j charges. 7 i

A thumb-operated lever 20 is fulcrumed between its ends at 21 upon alug 22 which is secured to and projects upwardly from the rim of the container 5, the outer end of this lever being positioned above the handle 6 so that it may readily be depressed by the thumb of the hand which grips'said handle. The inner end of lever 20 is formed with an opening 23 through which the upper end of the rod 15 passes, said rod end being provided with a head 21 orwithother provision for establishing a downwardly facing shoulder to overlie the lever 20. Depression of the v outer end of lever 20 raises its inner end, thereby raising the rod 15 against the action of the spring 18 and opening the valve 17. Provision is made whereby the notch 19 snaps into engagement with the guide 16 as soon as the valve 15 is completely raised,

thereby holding the valve open while the oil discharges. Upward movement of the outer end of lever 20, efiected by an upward push with the thumb, causes one edge of the opening 23 to abut the rod 15 and laterally force the latter to a sufficient extent to disengage the notch 19' from the guide 16, thereby allowing the spring 18 to again depress said rod and close the valve 17. V

In the'form of construction shown in Figs.

1, 2 and 3, the inner end25 of lever 20 is always declined toward the notched side of the rod 15. Consequently, while lever 20 is; being operated to raise the rod and the spring 18 is forcing downwardly upon said rod, the

head 24 has a tendency to slide down said inclined end 25. The result is that as soon as the notch 19 reaches the guide 16, the rod 15 is free to slide in the manner stated. Consequently, it will so slide and engage the notch'19 with the guide 16. Raising of the rod in this manner effects opening of the valve and discharge of the oil takes place,

and when said valve is to again be closed, it is simply necessary to force'upwardly upon the outer end of the lever 20. When this is done, the edge of tie opening 23 toward the center of the container 5, abuts the rod and due to the are on which the lever then sw1ngs,-said edge forces the rod'15 outwardly toward the container wall thereby disengaging its notch 19 from the guide 16 and al lowing the spring 18 to effect lowering of the rod and consequent closing of the valve.

In the form of construction shown in Fig.

,4, when the rodl5 nears its completely raised position, it binds vagainst theedge of the open ng 16" toward the container wall and also abuts the edge or" the opening 23 toward the center of the container 5. Hence, as the upperend of the lever swings outwardly about the fulcrum 21, the rod 15 is slightly sprung longitudinally as emphasized in Fig.

= The rod is thus placed under tension and as soon asthe notch 19 arrives at a sufiiciently high point, the rod straightens and effects engagement of said notch with the guide 16. When the oil has drained out of the container, upward movement of the outer end of lever 20 causes the edge of the opening 23 toward the container wall to thrust against the rod 15 thereby disengaging the notch 19 from the guide, 16 and allowing valve-closing under the influence of the spring 18.

It will be seen from the foregoing'that while the invention is exceptionally simple andinexpensive, it will be eff cient andin every way desirable. Qn account of thee isting advantages for the details disclosed, they are preferably followed. However,

- within the scope of the invention as claimed,

variations may be made.

I claim l. A. liquid dispensing device comprising a container having an open top and pro-,

vided in its bottom with an outlet, an upwardly opening valve for said outlet, a vertical rod carrying said valve and extend ng "to said open top of the container, fixed guides for the upper and lower portions of said rod, a thumb-operated lever iulcrumed between its ends upon the upper end of the container and having an open ng in lts nner end adapted to laterally force said rod and disengage its notch from said upper guide upon upward movement of said outer end of the lever from its valve-open position.

, 2. A structure as specified in claim 1; said inner end of said lever being declined toward the notched side of said rod when in valveopen position, whereby the downward force ofsaid spring upon the rod will then cause sliding of said shoulder down said declined lever end, thereby .eflecting lateral shifting of the rod to engage said notch with said upper guide.

In testimony whereof I have hereunto affixed my signature; 7
